My SSD has suddenly stopped working on macbook.

Hi,

Today I turned on my Macbook Pro with a CRUSIAL M500 Solid State Drive and then the spinning pinwheel shows up and I just turned off the computer. After that, my macbook dosen't recognize the ssd when it's conect with the internal SATA. I Installed my old HD and recovered the system, connected the ssd with a external case and it works. But only externally.The problem is, I dont even know if Crucial has support in my country.Some advice?
